61c6f0d190 net/mlx5e: TC, Refactor sample offload error flow
Refactor sample unoffload to be symmetric to sample offload.
Use the existing del_post_rule() to release the post rule.
Also mlx5e_tc_sample_unoffload() should not return post_rule
which is NULL when post actions are supported.
Sample offload works with this NULL because many places of the
code use IS_ERR() instead of IS_ERR_OR_NULL() to check rule is valid
and when rule is detected as sample offload the code is not using the
rule. Let's be persistent and avoid returning NULL anyway and return the
pre rule, like in CT case, which is not NULL.

Prabhakar Kushwaha says:

====================
qed: new firmware version 8.59.1.0 support

This series integrate new firmware version 8.59.1.0, along with updated
HSI (hardware software interface) to use the FW, into the family of
qed drivers (fastlinq devices). This FW does not reside in the NVRAM.
It needs to be programmed to device during driver load as the part of
initialization sequence.

Similar to previous FW support series, this FW is tightly linked to
software and pf function driver. This means FW release is not backward
compatible, and driver should always run with the FW it was designed
against.

FW binary blob is already submitted & accepted in linux-firmware repo.

Patches in the series include:
patch 1     - qed: Fix kernel-doc warnings
patch 2     - qed: Remove e4_ and _e4 from FW HSI
patch 3     - qed: split huge qed_hsi.h header file
patch 4-8   - HSI (hardware software interface) changes
patch 9     - qed: Add '_GTT' suffix to the IRO RAM macros
patch 10    - qed: Update debug related changes
patch 11    - qed: rdma: Update TCP silly-window-syndrome timeout
patch 12    - qed: Update the TCP active termination 2  MSL timer
patch 13    - qed: fix ll2 establishment during load of RDMA driver

In addition, this patch series also fixes existing checkpatch warnings
and checks which are missing.

Changes for v2:
 - Incorporated Jakub's comments.
   - New patch introduced to fix all kernel-doc issue in qed driver.
   - Fixed warning: ‘qed_mfw_ext_20g’ defined but not used.
   - Fixed warning related to kernel-doc wrt to this series.
   - Removed inline function declaration.

cfbe9b0021 Merge branch 'ipv6-ioam-encap'
Justin Iurman says:

====================
Support for the ip6ip6 encapsulation of IOAM

v2:
 - add prerequisite patches
 - keep uapi backwards compatible by adding two new attributes
 - add more comments to document the ioam6_iptunnel uapi

In the current implementation, IOAM can only be inserted directly (i.e., only
inside packets generated locally) by default, to be compliant with RFC8200.

This patch adds support for in-transit packets and provides the ip6ip6
encapsulation of IOAM (RFC8200 compliant). Therefore, three ioam6 encap modes
are defined:

 - inline: directly inserts IOAM inside packets (by default).

 - encap:  ip6ip6 encapsulation of IOAM inside packets.

 - auto:   either inline mode for packets generated locally or encap mode for
           in-transit packets.

With current iproute2 implementation, it is configured this way:

$ ip -6 r [...] encap ioam6 trace prealloc [...]

The old syntax does not change (for backwards compatibility) and implicitly uses
the inline mode. With the new syntax, an encap mode can be specified:

(inline mode)
$ ip -6 r [...] encap ioam6 mode inline trace prealloc [...]

(encap mode)
$ ip -6 r [...] encap ioam6 mode encap tundst fc00::2 trace prealloc [...]

(auto mode)
$ ip -6 r [...] encap ioam6 mode auto tundst fc00::2 trace prealloc [...]

A tunnel destination address must be configured when using the encap mode or the
auto mode.

This patch anticipates the support for the IOAM insertion inside in-transit
packets, by making a difference between input and output in order to determine
the right value for its hop-limit (inherited from the IPv6 hop-limit).

Input case: happens before ip6_forward, the IPv6 hop-limit is not decremented
yet -> decrement the IOAM hop-limit to reflect the new hop inside the trace.

Output case: happens after ip6_forward, the IPv6 hop-limit has already been
decremented -> keep the same value for the IOAM hop-limit.

This patch caches doorbell address directly in struct mlx4_en_tx_ring.

This removes the need to bring in cpu caches whole struct mlx4_uar
in fast path.

Note that mlx4_uar is not guaranteed to be on a local node,
because mlx4_bf_alloc() uses a single free list (priv->bf_list)
regardless of its node parameter.

This kind of change does matter in presence of light/moderate traffic.
In high stress, this read-only line would be kept hot in caches.

====================
Use netdev->dev_addr write helpers (part 1)

Commit 406f42fa0d ("net-next: When a bond have a massive amount
of VLANs...") introduced a rbtree for faster Ethernet address look
up. To maintain netdev->dev_addr in this tree we need to make all
the writes to it got through appropriate helpers.

This is the first installment of predictably tedious conversion.
It tackles:

  memcpy(netdev->dev_addr, something, ETH_ADDR)

and

  ether_addr_copy(netdev->dev_addr, something)

replacing both with eth_hw_addr_set().

The first 7 patches are done entirely by sparse.
Next 4 were semi-manual because the sparse conversion
resulted in errors.

16be9a1634 ethernet: use eth_hw_addr_set() - casts
eth_hw_addr_set() takes a u8 pointer, like other
etherdevice helpers. Convert the few drivers which
require casts because they memcpy from "endian marked"
types.

Manual conversions because we need to get to the member
which is inside an array to have a u8 pointer which
eth_hw_addr_set() expects.

fa8274b788 Merge branch 'ocelot-vlan'
Vladimir Oltean says:

====================
Egress VLAN modification using VCAP ES0 on Ocelot switches

This patch set adds support for modifying a VLAN ID at the egress stage
of Ocelot/Felix switch ports. It is useful for replicating a packet on
multiple ports, and each egress port sends it using a different VLAN ID.

Tested by rewriting the VLAN ID of both
(a) packets injected from the CPU port
(b) packets received from an external station on a front-facing port

Adding a selftest to make sure it doesn't bit-rot, and if it does, that
it can be traced back easily.

434ef35095 selftests: net: mscc: ocelot: add a test for egress VLAN modification
For this test we are exercising the VCAP ES0 block's ability to match on
a packet with a given VLAN ID, and push an ES0 TAG A with a VID derived
from VID_A_VAL plus the classified VLAN.

$eth3.200 is the generator port
$eth0 is the bridged DUT port that receives
$eth1 is the bridged DUT port that forwards and rewrites VID 200 to 300
      on egress via VCAP ES0
$eth2 is the port that receives from the DUT port $eth1

Since the egress rewriting happens outside the bridging service, VID 300
does not need to be in the bridge VLAN table of $eth1.

Looks like when I wrote the selftests I was using a network manager that
brought up the ports automatically. In order to not rely on that, let
the script open them up.
